CARRIAG E-CU RTAIN FASTEN ER.

SPEGIFICATIQN forming part of Letters Patent No. 403,388, dated May 14, 1889.

Application filed February 12, 1889. Serial No. 299,590. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL P. SCOTT, of Hillsborough, in the county of Highland and State of Ohio, have invented certain new and useful Improvements in Carriage-Curtain Fasteners; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which Figure 1 is a side view of my improved carriage-curtain fastener. Fig. 2 is a top view thereof, showing it indifferent positions by the aid of dotted lines; and Fig. 3 is a central vertical section through the same, showing its construction. Figs. 4: and 5 are details of various parts. Fig. 6 is a sectional detail View through the fastener, showing the pin disengaged. Fig. 7 is a perspective view of the sleeve detached.

This invention is a carriage-curtain fastener, and is an improvement upon the fastener for which I was granted Letters Patent of the United States March 19, 1889, No. 399,934; and it consists in the improved novel construction and combination of parts hereinafter described and claimed.

Referring to the drawings by letter, A designates the base of the button, preferably oval in cross-section and bored centrally, as at a, the upper end of this bore being enlarged, as at a B designates the adjustable head, also oval in cross-section and having its outer end rounded, as shown, to facilitate engagement or buttoning of the curtain thereon.

b is a central bore or chamber in said head, but not extending therethrough, being closed near the outer end of the head, as shown. This bore is about the same diameter as part a of bore a.

C designates a sleeve which is of a diameter to fit closely in bore b of head B, into which it is partially slipped, the outer end of the sleeve projecting beyond the face of head B a distance about equal to the depth of enlargement a of bore a.

D designates a stem, one portion of which extends through bore a of base A and through the sleeve G into head B. The portion of stem D projecting below the base may be screwthreaded, if desired, or otherwise adapted to engage the frame-work of a carriage to secure the fastener in position thereon. The end of the stem projecting through sleeve C and into head B is provided at diametrically-opposite points with ears or studs d cl, which are preferably formed integral with the stem. The bore of the projecting end of sleeve 0 is enlarged, as at c, and E designates a coiled spring surrounding stem D and entering enlarge ment 0 of the sleeve and enlargement a of base A. The upper end of sleeve C is diametrically notched, as at E E and e e, the notches E E being in line with each other and at right angles to a line drawn between notches e e.

The parts, being assembled, are put together as follows: Sleeve C is slipped on pin D with its notched end adjoining the lugs of said stem. The head B is then slipped over the notched end of the sleeve and stem to the position shown, and by giving the head a lateral blow with a hammer it is compressed upon the sleeve sufficiently to bind the latter securely therein. The sides of the sleeve might be roughened to facilitate this binding. Spring E is then slipped on the stem, and then base A is put thereon and moved up until the projecting end of the sleeve engages the mouth of enlargement a, thereby completely hiding spring E from view. A blow on the side of base A binds the stem securely thereto. The spring E tends to separate the sleeve and base, while the head moves with the sleeve, and the action of the spring causes the lugs of stem D to engage the notches in sleeve C, sufficient space being left between the end of the sleeve and head of opening I) to allow the sleeve and head B to be moved up and down on the stem, and thus engage or disengage the lugs and notches. This movement is not sufficient, however, to permit the sleeve to entirely disengage enlargement a. Obviously, therefore, if the sleeve has been properly adjusted in head B, the latter can be set parallel with base A, or at right angles thereto, and locked in either position until forcibly disengaged. The sleeve C might be shouldered exteriorly, as

indicated at c, Fig. 5, which shoulder abutting against the face of head B would regulate the insertion of the sleeve therein; or the bore of the head might be shouldered, as at b, Fig. 4, for the same purpose.

The advantages of the present construction of the fastener over that shown and described in my patent above referred to are, that its sleeves cannot accidentally become twisted or turned in the bore so as to prevent proper engagement of the lugs and notches. The flange around the mouth of the enlargement of the base-bore being omitted, the base can be readily cast, and the fastener is more durable and stronger and is more cheaply made, while the spring and locking devices are covered and protected.

Having thus described my invention, I claim- 1. The combination of the base and the head having a central bore with a sleeve secured in the bore of the head and projecting therefrom and having notches in its inner end, the stem secured to said base and passing through said sleeve, having lugs on its upper end engaging the notches of the latter, and the coiled spring interposed between the bore and head, all substantially as and for the purpose set forth.

2. The combination of the base and the head, each having a central bore, substantially as described, the tubular sleeve secured in the bore of the head and having one end project 3. The combination of the base having a said base, having lugs on its outer end, 'with'.

the sleeve 0, having notches in one of its ends and an enlarged bore at its other end, and a coiled spring partly entering the enlarged bore of the sleeve and the bore of the base,

all substantially as set forth.

5. The combination of the base having a central bore enlarged at its outer end and a head having a chamber with a stem having lugs on its outer end, a sleeve, 0, slipped on said stem and secured in the chamber of head A, but projecting therefrom, said sleeve having notches in its innerend to engage the lugs of the stem and an enlarged bore at its outer end, and a coiled spring on said stem between the sleeve and base, all substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

SAMUEL P. SCOTT.
